Abstract
The present invention relates to a method for spraying a copper plate of a crystallizer through supersonic flames, which is characterized in that the present invention has the steps that first, the surface of the copper plate of the crystallizer is carried out cleaning and sand blasting treatments by using a conventional cleaning process step; then, hastelloy particles of 50% to 95% according to the percentage of the total mass is take out, alumina particles of 5% to 50% are added in the hastelloy particles and uniformly mixed, and desired spraying paint is obtained; next, the obtained spraying paint is arranged in supersonic speed spraying equipment to carry out the spraying on the surface of the copper plate of the crystallizer according to the conventional process step. Because the present invention adopts a method that supersonic flame spraying equipment is used for strengthening the surface of the copper plate of the crystallizer after right amount of alumina materials are added in hastelloy materials to obtain uniformly mixed paint materials, after the use of the method of the present invention, the bond strength of the spraying layer is enhanced, the spraying quality of the spraying layer is effectively ensured, and the problem that the hastelloy particles stick on a mouth, so the supersonic speed flame spraying equipment can not be used for strengthening the copper plate of the crystallizer is solved.
Description
Technical field
The present invention relates to a kind of method of supersonic flame spraying crystallizer brass plate.
Background technology
Advantages such as flame velocity is fast, temperature is low owing to having for the hypersonic flame spraying technology, and anchoring strength of coating height, coated component can not produce decomposition, and operation is simple, convenient, thereby, be particularly suitable for spraying some sintering metals.At present, the method of copper plate of crystallizer surface strengthening is more, wherein, adopting the nickel-base alloy particle is main spraying raw material flame spraying method, current general less use, reason is because the easy oxidation of copper plate of crystallizer, makes that to utilize spraying method to obtain Bond Strength of Coating not high always, the as easy as rolling off a log result of use that influences copper plate of crystallizer.Secondly, be steady operation for a long time because nickel-bass alloy material takes place easily that coating particles is bonded at the nozzle internal surface, need often clear up to the nozzle of spray gun, influenced the efficient of spraying work and the quality of the work of spraying.
Summary of the invention
The object of the present invention is to provide a kind of bonding force that can effectively solve the sticking nozzle of coating particles and improve coating and crystallization copper coin, and operation is simple, the method for high efficiency supersonic flame spraying crystallizer brass plate.
Technical scheme of the present invention is achieved in that
A kind of method of supersonic flame spraying crystallizer brass plate, its characteristics are to comprise following method steps: at first with conventional cleaning process the surface of copper plate of crystallizer is cleaned and sandblasting; Secondly, get nickel-base alloy particle 50%～95%, and add 5%～50% alumina particle and mix, obtain required spray material by total mass per-cent; Then, with obtaining pack in supersonic spray coating equipment operation routinely of spray material the surface of copper plate of crystallizer is sprayed.
Wherein, the better quality per-cent of the spray material that above-mentioned mixing obtains is respectively: nickel-base alloy particle 80%～92%, alumina particle 8%～20%.
The best in quality per-cent of the spray material that above-mentioned mixing obtains is respectively: nickel-base alloy particle 90%, alumina particle 10%.
The present invention owing to adopt adds an amount of alumina material in nickel-bass alloy material must mix the method for utilizing supersonic velocity flame plating equipment that the surface of copper plate of crystallizer is strengthened behind the coating material of obtaining, make the present invention effectively utilize the fusing point height of aluminum oxide and the supersonic flame temperature is lower, alumina particle not only can not melt but also can also obtain spraying rate faster in supersonic flame, one side makes alumina particle constantly wash away the internal surface of nozzle and the nickel-base alloy particle can not bondd at the nozzle internal surface of spray gun, also make alumina particle constantly beat surface and coatingsurface on the other hand at copper plate of crystallizer, make copper plate of crystallizer and coating expose active and clean surface, thereby reach the technique effect that improves Bond Strength of Coating as whole.And in spraying process, the ball blast effect of alumina particle can also be played the internal stress that reduces coating, helps to improve the effect of coating's adhesion.And in the process of spraying, alumina particle is not fusing almost, thereby can not remain in the performance that influences coating in the coating.
Below the present invention is described in further detail.
Embodiment
The method of a kind of supersonic flame spraying crystallizer brass plate of the present invention, it comprises following method steps: at first with conventional cleaning process the surface of copper plate of crystallizer is cleaned and sandblasting; Secondly, get nickel-base alloy particle 50%～95%, and add 5%～50% alumina particle and mix, obtain required spray material by total mass per-cent; Then, with obtaining pack in supersonic spray coating equipment operation routinely of spray material the surface of copper plate of crystallizer is sprayed.For making copper plate of crystallizer can obtain the coatingsurface of better quality, the better quality per-cent of the spray material that above-mentioned mixing obtains is respectively: nickel-base alloy particle 80%～92%, alumina particle 8%～20%; Its best in quality per-cent is respectively: nickel-base alloy particle 90%, alumina particle 10%.Like this, make the present invention effectively utilize the fusing point height of aluminum oxide and the supersonic flame temperature is lower, alumina particle not only can not melt but also can also obtain spraying rate faster in supersonic flame, one side makes alumina particle constantly wash away the internal surface of nozzle and the nickel-base alloy particle can not bondd at the nozzle internal surface of spray gun, also make alumina particle constantly beat surface and coatingsurface on the other hand at copper plate of crystallizer, make copper plate of crystallizer and coating expose active and clean surface, thereby reach the technique effect that improves Bond Strength of Coating as whole.And in spraying process, the ball blast effect of alumina particle can also be played the internal stress that reduces coating, helps to improve the effect of coating's adhesion.And in the process of spraying, alumina particle is not fusing almost, thereby can not remain in the performance that influences coating in the coating.
Implementation example:
Adopt supersonic velocity flame plating equipment spraying nickel-base alloy to strengthen the big copper plate of crystallizer of 0.25m * 1m, in 90% nickel-base alloy particle, add 10% alumina particle by mass percentage, mix and obtain required spray material, the nickel-base alloy that then copper plate of crystallizer through bright and clean processing is sprayed and do not add aluminum oxide compares.Added and once sprayed the big copper plate of crystallizer of 0.25m * 1m behind the alumina particle, the sticking mouth phenomenon of nozzle has not taken place, and through recording Bond Strength of Coating greater than 70Mpa.And, in 90% nickel-base alloy particle, add 10% alumina particle, after record that alumina particle is residual in the coating has only 0.2%～0.3%, fully coating performance is not constituted any influence.And the nickel-base alloy that does not add aluminum oxide is when spraying the big copper plate of crystallizer of 0.25m * 1m with same supersonic spray coating equipment, the nozzle of spray gun sprays to three/for the moment sticking mouth just takes place, the cleaning of need stopping is after having sprayed, through recording Bond Strength of Coating less than 50Mpa.Thereby, after using method of the present invention, not only Bond Strength of Coating can have been obtained improving greatly, guarantee the coating quality of coating effectively, but also solved the problem that to use supersonic velocity flame plating equipment that copper plate of crystallizer is strengthened because of the sticking mouth of nickel-base alloy particle effectively.
